USS ATA-215 was an ATA-214-class tug of the United States Navy built near the end of World War II.

Post-war she was assigned to the Finn Ronne Antarctic Expedition where she became stuck in the ice for 12 months before returning to the United States for decommissioning.

Paloverde, originally designated YN–86, was laid down on 19 July 1943 as AN–65 by Snow Shipyards, Inc., Rockland, Maine; renamed and redesignated ATA–215 on 12 August 1944; launched 2 September 1944; sponsored by Miss Patricia Adams; and placed in service 17 December 1944.

Then, getting underway for the U.S. West Coast, she transited the Panama Canal 19–20 February and arrived San Pedro, California, 19 March.

On 25 January 1947 Edith Ronne rechristened ATA-215 the Port of Beaumont, and the ship shoved off with 21 explorers for the Antarctic.
